comparatively inexpensive separating apparatus, whereby the sweepi'ngs are with little labor and conveniently assorted, and dustand other foreign matter separated therefronn Another object of the invention is to con struct a device which separates the bent and other pins not fitted for userliom the salable articles. v V

With these and other objects in view, which will more fully appear asthe nature of. the intention is better understood, the same consists in the con'ibination, arrangement and construction of parts hereinafter described, pointed out .in the f appended claims and illustrated in the accompanying drawings, it being understood that lllldllychanges may be made in the size and proportion of the several parts and details of construction within the scope of the ap pended claims, without departing froin the spirit or; sacrificing any of. the advantages of the invention. I

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation f a sepaating apparatus constructed in accordance with the present invention; Fig. 2 is a section taken on line 2-2 of Fig. l; and Fig. 3 is a section taken'on line 33'of Fig. 2.

In the drawings, the numeral 11 indi cates the side members of a frame,'which are connected by transverse tiejrodslil, or otherwise. t On these side frame members are formed bearings 13, in which is rotatably jouirnaled a horizontally extending transverse shaft 14', to which is fixed a drum 15. The heads 16 of this drum are imperforate, while the cylindrical wall ll" thereof is made of some foraniinated material, for instance wire fabric. A portion of the cylindrical wall of the drum, denoted by the numeral 18 (Fig. 3), is de tachable, to permit of access to the drum, into which the sweepings are placed. The portion 18 forms thus a, cover, which may be held in position upon the drum proper by any suitablelocking means, denoted in the drawings 'by the numeral 19. On the interior of the drum are formed radially extending ha'flles 20 which have a tendency to carry the sweepings in the drum upwards. .The drum is disposed within a casing 21.,part of the side walls of which is formed by the fiame'members. 11. The

bottom 22 of this casing-is slanting as clearly. shown". in-

.l and 3 of ,the drawii'igs and provided with an outlet. opening :23, that extends, from side to side of the casing. Theftop portion EFL-of the casing is in the form of a cover, that is hinged at 25 to the side frame memhers ll. By lifting this cover, access may'v be had to the drum of the separatingdevice. 'The casing is providedwitha nipple 26, 'to which may be attached the suction pipe of an airpump, which, when inoperation, removes from the casing dust'and small material, as the same is separated fron ithe sweepings and moves through the foraminte in the cylindrical wall of the drum toward the'out-letopening 23 of the casing.

The pins, which are separated in anianner hereinafter to be described from the sweepings in thedruni 15, slide down the inclined bottom of the casing 21 and are discharged. through the outlet opening 23 onto abelt conveyor 28, comprising two rollers indicated at 29 and 30,.whichare. rotatably. mounted in a frame 31, inclnd ing two side members 32 connected by tie rods 33. Over these rollers runs a plu- -1ality of belts 3d, separated by vertical slats 35, which project above the belts. The slats are attached to a plate member 36, which is supported by transverse strips 37 These strips are secured to the side members The distance between. each two adjacent slats 35is a few tinies larger than the diameter of the head of an individual pin, but smaller than the length of a pin. The acting portion of the belt conveyer is inclined forwardly, as clearly appears from Figs. 1 and 3 of the drawings, and the free edges 35 of the slats slant also forwardly, their front edges 39 projecting a considerable distance in front of the roller 30.

In front of the belts .34 is placed aboard a l), which slants from the roller3(). down wards, there being a gap 'between'the lastmentioned roller and the said board. Below this gap is provided an inclined board l1, and in front of the front edges 39 of the slats 35 an inclined board 42. The boards 40, 41 and -12 are mounted on the frame 31. The drum and conveyer are actuated from Hit) any suitable source of power, driving a belt 43, which runs over a'pulley ie on a driving shaft 45, the latter being journaled in a bearmg LG on one of the side frame members 11.

To the same shaft is fixed a gear 47, in mesh' with a gear 4:8, keyed to the drumshaft lt,

'The gear dimeshes also with a gear 50' on 1 cover Q-l of the casing 21, the drum with tl gear 48 thereon may be removed from the de vice. )Tlie frame 31, with the elements mounted thereon, is also removable as a unit, from the side frame members 11. This becomes necessary in case one of the belts 3a: is

torn and is to be replaced. in order to permit the frame 31 to be removed, each of the side frame members 1111s provided with a slot- 52, throughwhich the shaft '51 ,n'ray be inserted; I ."The operation of this device is asffo lows: The sweepings are placed into drum 15. "After the cover 2% of the c: 21 has been placed to closing position, driving shaft 45 is actuated. The drum thus rotated, the battles QO-therein carrying the sweepings continuously upwards, they dropping, when they reach in their upward travel a certain level, back to the lowermost point of the drum. While being thus carried upwards and dropping back to the lowermost point of the drum, dust and other like particles are separated from the sweepin'gs-by the air pump, and carried away through the nipple 26. Such dust and other like particles, which find their way through the foramina in the drum onto the slanting bottom 22, of the casing 21, are also removed by the air pni'np'p [-Pins and needles pass through the forai'ninated cylindrical wall of the drum, the mesh of thescreen of which is larger than the. head of a pin. The pins and needles slide down the inclined bottom 22 of the casing 21 and pass through the outlet opening 23 in the said bottom onto the conveyor 28.7 On this conveyer the pins are caused to travellengthwise, that is to say with their longitudinal axes arrangedparallel or substantially parallel to the direction of travel,

for the reason that the slats 35 are disposed at a distance from each other which is smaller than the length of a pin. Such pins which are bent cannot drop onto'the conveyer belts, but slide down on the slats 35. The

perfect pins move over the gap between the conveyor belts and the board L0 onto thesaid board, and slide down the board into a The bent pins, on

this manner the perfect pins and needles are separated from those. which cannotbe used again con'nnercially.

tor the sxi'eep ngs have been treated for some one in the manner lndicated, theap- )oil atns stow tied and the material removed l or on another machine.

ii hat I claim is 1 i clined belt conveyer, longitudinally extending parallel slats dividing the acting portion of said conveyer, the distance between adacent slats being smaller than the length of a pin, a slanting board adjacent-the discharge end of said conveyor, said slats projecting forwardly of said conveyer, and a tending ends of said slats.
